IMPROVEMENT IN CIL-CANS.

Specification forming part of Letters Patent No. 179,710, dated July 11, 1876; application filed December 9, 1875.

To all whom it may concern:

Be it known that We, ZARA C. MARLATT and JOHN I. Cook, of Pittsburg, in the county ot' Allegheny and State ot' Pennsylvania, have invented certain new and useful Improvements in Oil-Cans 5 andwe do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the'art to which it appertains to make and use the same,-ref'erence being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention has in view the production of an oil-can for lubricating light machinery, that shall be strong and cheap and possess the advantage of indicating at all times the quantity of oil contained in it.

The improvement consists in making the can of tempered glass sufticiently thick to be strong, and provided with a metallic spring bottom peculiarly arranged in connection with an annular glass bottom, and having a removable met-al nozzle, as will be herewith described, and the invention pointed out distinct ly in the claim. v

Figure l represents a sectional View of our improved lubricating-can, indicating the manner in which the parts are connected. Fig. 2 is a broken sectional view, representing a inodi tication in the manner of uniting the glass and metal bottoms ot' the body ofthe can.

A, in Fig. 1, represents thc body ot' the can, made of any of the usual forms and of tempered glass. Its mouth is provided with a thread, ufon which is screwed the metallic nozzle B. To make a perfectly tight joint, a leather washer, b, may be placed upon the top of the mouth, and be clamped by a shoulder in the nozzle, as represented. `O is a metallic spring-bottom, convex on its under surface, and having a flanged rim for insertion in the recess c, made for it in the bottom of the body A.

Upon placing the metal bottom in position, cement is poured into the recess, and the two parts are tirmly connected, making an oilproof joint.

lo complete the device, the glass bottom D, having a thread on its periphery, is screwed into a corresponding thread on the inside ot' the bottom edge of the body A. This glass bottoni has a central orilce sufficiently large to allow the end of the thumb to press upon the metal spriiig-bottom and cause the oil to flow.

In Fig.2 another manner of attaching the glass bottom is represented, similar to the one just described, with this exception, that the bottoni, instead of being screwed in, ts in and is cemented.

We are aware of the mode of making and attaching bottoms of hollow pressed articles of glassware by forming the bottoni separately n a mold, and uniting the open lower end ofthe article thereto by a fused joint or union, and consequently we disclaim such inode ot' connection; but

What we do claim as new, and desire to secure by Letters Patent, is

An oil-can whose body is made of tempered glass, provided with a metallic nozzle and a metallic spring-bottom, protected by an annular glass bottoni connected thereto, as and for the purpose specified.

In testimony that we claim the foregoing as our own we affix our signatures in presence of two witnesses.
